ブレードに大きな損傷を与える可能性が大である。As described above, in the steam-cooled combustor of the gas turbine, a pipe for cooling steam is provided on the wall of the transition piece, and this steam pipe is fixed by a pipe support. The support is fixed to the wall of the transition piece by welding and supported. This pipe support has a U-shaped upper and lower support, in which a steam pipe is sandwiched via a spacer inside, and is tightened with bolts and nuts, and the pipe support is fixed to a transition piece wall surface. During operation of the combustor, combustion vibration is generated, and due to vibration fatigue, such a pipe support may cause the mounting member on the wall of the transition piece to come off. In some cases, for example, if the bolts and nuts come off due to vibration, the clamps may fall out of the piping, and these components may enter the turbine section together with the combustion gas, and in such a case, the gas turbine blades may be seriously damaged. The sex is great.

Even if the two welds 82 and 83 are dislocated due to combustion vibration or the like, since the outer mounting member 31 is fixed to the ring 32, it does not fall off and the ring 32 is connected to the pipe 101.
It does not fall off because it is inserted through.

ード等の損傷を防止することができる。The pipe support of the gas turbine steam-cooled combustor according to the present invention is a ring which is inserted into the outer periphery of the steam pipe and is fixed to the pipe, a U-shaped member, and an inner curved surface of the member. An outer mounting member is provided which is in contact with the ring, fixes the ring, and is fixed to the transition piece wall surface at both ends opposite to the curved surface. With such a pipe support, the steam pipe is supported on the wall surface of the transition piece by the outer mounting member, and the outer mounting member is fixed to the ring, so that the outer mounting member comes off the wall surface due to fatigue such as combustion vibration. Even so, the ring supports the outer mounting member on the steam pipe, and the detached member does not fall off the pipe. Therefore, the dropped members do not enter the gas passage of the gas turbine, and damage to the blades and the like can be prevented.
